请教AWS大神一道题目

luluwatermelon

在做一个project，不是编程出身，所以软件方面很弱。
有两个要求，一是要在AWS上host 一个static website, integrated with React.js, 二是要实现一个callback function, which return some simple data. Callback 的code 是python编写的。
问题来了，我知道如何在S3上host static website, 也需要用Lambda来跑python code, 但是trigger 是什么呢？API gateway么？

要求是The callback function is some Python code. It can't be executed in the browser, so need to be hosted
somewhere that it can execute in response to a web request. 那么是否是API gateway接收到的http request去trigger lamda 上面的python code?

一点思路都没有，请大家帮帮忙，谢谢。

从你提供的题目字面上看，你的理解没问题，就是api gateway接收request然后交给lambda function处理

谢谢！我可能要去看下developer 的course才知道具体要怎么操作

或着考虑一下 Customizing Content at the Edge with Lambda@Edge
https://docs.aws.amazon.com/Amaz ... da-at-the-edge.html

Lambda@Edge is an extension of AWS Lambda, a compute service that lets you execute functions that customize the content that CloudFront delivers. You can author Node.js or Python functions in one Region, US-East-1 (N. Virginia), and then execute them in AWS locations globally that are closer to the viewer, without provisioning or managing servers. Lambda@Edge scales automatically, from a few requests per day to thousands per second. Processing requests at AWS locations closer to the viewer instead of on origin servers significantly reduces latency and improves the user experience.

谢谢提供思路
Run Python code at Edge locations 应该更好实现一点，因为还有一个要求就是要用CDN去distribute website globally, 所以也是要用到Edge location的

这个需求挺奇怪哈，居然规定做法，学校作业吗？

frontend: browser <-> S3
backend: browser <-> api gateway <-> lambda (python)

or implement everything on ec2
